To use these earrings, simply insert the post through your earlobe hole. Make sure the backing is secure to prevent the earrings from falling off. When it comes to maintenance, use a soft, dry cloth to gently wipe the earrings after each wear to keep them shiny. Avoid exposing the earrings to harsh chemicals like perfume, hairspray, or cleaning agents as these can damage the gold plating. If you're not wearing the earrings, store them in a jewelry box or a soft pouch to protect them from scratches. And remember, if your ears have any irritation from these earrings, you can get a full refund.
